Building ₹1 Crore in 20 Years — Worked Example
Manish, a 25-year-old junior architect in Jaipur, earns ₹30,000/month. He commits ₹10,810 — about 36% of his income — towards a ₹1 Cr corpus by age 45. The maths works strongly in his favour: his total outlay over 20 years is just ₹25.94 L, but compounding generates ₹74.06 L — nearly 3x his contribution. This is the magic of a 20-year horizon versus 10 years: the required SIP drops from ₹44,762 to just ₹10,810, a 76% reduction. Manish chose a single Nifty 50 index fund in direct plan for simplicity. His plan has a built-in step-up: as his architecture career progresses (expected salary trajectory: ₹30K → ₹50K in 5 years → ₹80K in 10 years → ₹1.5L in 15 years), he will increase SIP proportionally. With a 10% annual step-up, the actual corpus at year 20 would be approximately ₹2.02 Cr — well beyond the ₹1 Cr target, giving him a comfortable margin for inflation or early retirement.

Frequently Asked Questions
Can a ₹30,000/month salary support a ₹10,810 SIP?
₹10,810 is 36% of a ₹30,000 salary — aggressive but doable if you live frugally. The key is that your salary will grow. In 5 years at ₹50,000/month, the SIP becomes a comfortable 22%. Start tight, knowing it gets easier. If it is too much, start at ₹7,000 and step up.
₹1 crore in 20 years vs 10 years — why is the SIP so different?
10-year plan: ₹44,762/month. 20-year plan: ₹10,810/month. The 76% reduction comes from 10 extra years of compounding. Those 10 years contribute ₹68.89 L more in gains. This is why starting early — even with a lower amount — dramatically beats starting late with a higher amount.
Should a young investor put 100% in equity for a 20-year SIP?
For the first 15 years, 100% equity is justified — you have time to recover from any crash. From year 16 onward, start introducing 10-20% debt allocation. By year 20, aim for 70% equity, 30% debt. This protects your near-₹1 Cr corpus from a last-minute market correction.
What if I want to buy a house in year 10 — can I break the SIP?
You can redeem anytime, but breaking a 20-year SIP at year 10 means you only have about ₹22 L (roughly 22% of the final target). Instead, take a home loan for the house and continue the SIP. The SIP's 12% return exceeds the home loan's 8.5% rate — it is mathematically better to invest and borrow.
